LIQUID CARBONATING AND DISPENSING APPARATUS- Specification of Letters Patent.

" Patented Aug. 1, 1905.

Application filed April 4, 1906. Serial No. 253,748.

To all whom it may concern.-

Be it known that we, JOHN F. YOUNGBLOOD and DAVIDYOUNGBLOOD, citizens of the United States, residing at Troy, in the county of Pike and State of Alabama, have invented certain where in the same apparatus the liquid will be carbonated while under an artificially-produced low temperature and after being carbonated may be drawn through a coil sub-- jected to an artificiallyproduced low temperature and then dispensed through a draft-tube in communication with said coil either into bottles or into glasses, said parts being constructed and arranged so as to economize space and render them most eflicient for the purposes in View and in which also the stand containing said parts may serve as a cooling or refrigerating chamber.

To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in features of construction and arrangement of parts hereinafter particularly described and then sought to be clearly defined by the claims, reference being had to the accompanying drawings, forming a part hereof, and in which- Figure 1 is a front elevation of the apparatus; Fig. 2, a vertical section thereof, and

Fig. 3 a detail sectional view of a portion of the dome.

In the drawings the numeral 1 designates a stand of suitable construction having a top 2 and a compartment 3, which stand will support the carbonator and reservoir or fountain and cooling means.

The numeral 4 designates a cylinder or shell supported within the compartment 3 from the top 2, and the numeral 5 designates an inner cylinder or shell fitting within the shell 4 so as to leave a space 6 between the two cylinders or shells and which'will constitute a reservoir for the carbonated liquid, the connection between the two shells being made with a tight joint in any suitable manner.

The numeral 7 designates a carbonatingdome of approved pattern-for instance, such a dome as is illustrated in Letters Patent No. 7 58,403, granted to us April 26, 1904:which dome is supplied with water through the supply-pipe 8 and is supported at the top of the inner and outer shells or cylinders 4 and 5, so as to communicate with the space 6 between the two shells.

The numeral 9 designates a pipe in communication with the space 6 and leading from a suitable source of supply of carbonic-acid gas, and the numeral 10 designates a watergage in communication with the lower and upper portion of the space 6 through pipes 11 and.12 for the purpose of indicating the depth'ot' the liquid in the space or reservoir 6. Within the shell 5 and coiled around the sides thereof is a pipe 1 3, having its lower end in communication with the bottom of the reservoir 6 and its upper end extended through the walls of the inner and outer shells and connected by a pipe 14: with a draft-tube 15, suitably located for dispensing the liquid drawn from the reservoir 6 through the coiled pipe 13, the liquid being dispensed through the draft-tube either into bottles for containing carbonated liquid or into glasses at a soda-fountain. The liquid which percolates through the carbonating-dome absorbs the carbonic-acid gas introduced into the space or reservoir 6, and the absorption is increased by the low temperature produced by filling the inner shell 5 with ice, and the carbonated liquid in the reservoir 6 is maintained at a low temperature by the ice in the inner shell, thereby maintaining the liquid in the best condition for the greatest absorption of gas and allowing it to be drawn from the apparatus through the draft-tube at a low temperature and without the escape of gas from the water. By locating the coil 13 inside the inner shell the carbonated liquid after it leaves the reservoir 6 is compelled to travel the length of the coil, so that it is subjected to a low temperature after it leaves the reservoir and before it reaches the draft-tube, thus further insuring the more thorough absorption of the gas by the liquid and preventing the separation of the two between the time the liquid leaves the carbonating apparatus and reaches the draft-tube.

The numeral 1 6designates a valve-controlled pipe for draining the inner shell when the same is to be emptied or cleansed, and the numeral 17 designates a valve-controlled pipe leading from the reservoir 6 for emptying the same when necessary for any purpose, and the numeral l8 designates a cover for the top of the inner shell or cylinder 5. This cover also serves as a support for syrups that it may be desired to keep cool, and the compartment 3 serves for the storage of diflerent articles that it may be desirable to keep in a cooling or refrigerating chamber, said compartment having its temperature kept to a low degree by the cooling influence of the ice in the shell or cylinder 5.

The stand which supports the different parts described may be provided with an external casing of any ornamental design preferred, which it is not necessary to illustrate, as the same forms no part of the invention, and the parts described may be used in connection with a sodawater-dispensing fountain, with its usual accessories.

The apparatus described is not only simple in its construction and of few parts, but is also most eificient for the purposes in view.

While we have described with particularity the preferred details of construction and arrangement of parts, yet there may be changes made in their form and arrangement and essential features of the invention still be retained.

Having described our invention and set forth its merits, what we claim is 1. In a liquid carbonating and dispensing apparatus, the combination of a liquid-containing reservoir composed of an inner and an outer vessel spaced apart to form a liquid-containing chamber between the two vessels, the inner vessel constituting a chamber to hold a refrigerant, a carbonating-dome in communication with the chamber between the two vessels, means for supplying a carbonating-gas to the liquid passing from the dome into the chamber between the two vessels, means for conducting the carbonated liquid from said chamber and through the refrigerantcontaining chamber, said means consisting of a pipe coiled within the inner chamber and in communication with the space between the two chambers, and means for conveying said liquid to its point of discharge, substantially as described.

2. In a liquid carbonating and dispensing apparatus, the combination of a liquid-containing reservoir composed of an inner and an outer vessel spaced apart to form a liquid-containing chamber between the two vessels, the inner vessel constituting a chamber to hold a refrigerant, a carbonating-dome in communication with the chamber between the two vessels, means for supplying a carbonating-gas to the liquid passing from the dome into the chamber between the two vessels, a pipe loading from said chamber and coiled within the refrigerant-chamber of the inner vessel, means in communication with said pipe for conducting the carbonated liquid to its point of discharge, and means for draining the inner and outer vessels, substantially as described.

In testimony whereof we afiix our signatures in presence of two witnesses.
